Zimbra TGZ facts
Zimbra stores mail in TGZ archives that no desktop client opens. This tool reads the archive, or signs in to the mailbox, and exports the data to formats Outlook, Thunderbird and cloud services accept. The source stays as it was.

Why Teams Use a Zimbra TGZ Converter
Companies leave Zimbra for Outlook, Gmail or Microsoft 365, and admins need archives that open on a desktop. TGZ opens nowhere outside Zimbra. A batch conversion takes minutes where file by file exports take days.
Core features
Install, connect, select data and export.
Install
Run the setup file and open the Zimbra TGZ Converter on Windows. The software waits for a mailbox or an archive.
Folder selection
Go to Open, then Email Account, and enter the Zimbra credentials. The tool connects and lists every folder. A TGZ file loads the same way.
Message preview
Open any email or attachment before export. Search by text, phrase or keyword finds specific items, and the folder list shows the count of read and unread messages.
Selective backup
Filters keep exports small, so the converted mail is easy to find later.
Output options
Open the Export tab, select a format, apply filters and click Save. The converted data lands at the chosen path.
Before the export
Three short checks keep the output clean.
Source data
Copy the TGZ First
Store a copy of the TGZ archive on a safe drive. Conversion never touches the archive itself.
Data scope
Mailbox or archive
Convert a live mailbox with login details, or use a TGZ file with no login. Select folders only to keep the output focused.
Destination
Set the target format
Local disk formats cover PST, EML and MBOX. Cloud targets ask for login details once and then take the batch.
Moving finished files into mail apps is covered in Import Zimbra TGZ to Outlook and Import Zimbra TGZ to Thunderbird.

Corbett Zimbra Converter Tool Worked Well for me. This software allows me to export the Zimbra TGZ file without any error. Additionally, I loved the simple way to execute the conversion process with advance data filters. Thank you for this secure and advance automated solution.
Incredible Software! The TGZ File Converter performs the Zimbra conversion efficiently. It allows me to export associated email addresses and contacts. I tried the demo edition of the software and purchased the licensed key to perform conversion of over 1000 Zimbra emails.
The Zimbra TGZ Converter is an all-in-one solution for us. It helps us to export the complete Zimbra Database to cloud platforms. My business has been using Zimbra for the last five years, and we are planning to switch, and this software made it possible. Great way to convert your data files.
